 What Is an Orifice Plate Flange Assembly?

An Orifice Plate Flange Assembly is a precision flow measurement device used to determine the flow rate of liquids, gases, and steam in a pipeline. It combines a precision orifice plate with matching flanges, pressure taps, gaskets, bolts, and nuts to create a complete assembly for differential pressure flow measurement.

When fluid flows through the pipeline and passes through the orifice plate, a pressure differential is created between upstream and downstream points. This pressure drop correlates with the flow rate based on fluid dynamics principles, allowing accurate measurement using differential pressure transmitters.
